LT		 1/*=============================================================================
2 *
3 * A PCMCIA client driver for the Raylink wireless LAN card.
4 * The starting point for this module was the skeleton.c in the
5 * PCMCIA 2.9.12 package written by David Hinds, dahinds@users.sourceforge.net
6 *

23 * Changes:
24 * Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 08/08/2000
25 * - reorganize kmallocs in ray_attach, checking all for failure
26 * and releasing the previous allocations if one fails
27 *
28 * Daniele Bellucci <bellucda@tiscali.it> - 07/10/2003
29 * - Audit copy_to_user in ioctl(SIOCGIWESSID)
